Best Air Conditioning Leak Detection Tools

Inficon 718-202-G1 Gas Mate Combustible Gas Leak Detector
INFICON raises the bar on combustible gas detectors with the next-generation GAS-Mate, the ideal tool (or locating leaks in combustion appliances, such as natural gas or propane-fired heating systems, or gas valves, regulators and pipelines.
"I originally used a gas rated teflon tape on all of my joints, however I came to find out through watching my meter that I was losing a very small amount of gas somewhere in the re-piped lines. This worked well when when I had considerably large leaks, and you can easily see all areas of the joint (back side of elbow and unions), but for micro leaks the soap and bubbles didn't work for me at my typical natural gas pressure (1/2psi or less). If you planning to re-pipe natural gas line, or you have some natural gas lines in your home that you want to check to be sure, this is a great product."
"Using the Gas Mate I was able to pinpoint the source of the leak to a particular fitting, The detector lit up like a Christmas tree even though it was very hard to detect with soap water."
"This was great found my gas leak in my RV. After I fixed it I use the most sensitive setting and found a bad connection that I may not have found."
"One thing I don't like is that it will produce a continuous tone while it is warming up (which can take 10-30 seconds depending on temperature)."
"I used the gas company $3000 hand held meter, which also failed to find the same leak."
"I love this Gas Mate, I have used it on my water heater,pool heater and my RV."
"Just 34 ppm of methane that came out of the pressure regulator vent sent the the Inficon's led readout to max! The pressure regulator venting "leak" can be normal when the climate temperature is fluctuating if your gas company does not periodically adjust line pressure throughout the year. If you smell or detect gas from there, you should also call your local gas company just to have them check it out."
"I can't smell gas well enough to locate it - this device is exactly like the pros use and it is accurate, easy to use and just saved me a lot of investigative hassle trying to find and then determine I had fixed the leak."

"I bought this for my husband a few days ago, and it arrived today. When you open it up, it looks like it only holds 2, but you have to pull it out and put 2 more batteries on the back side of the holder."
"This is going to be a lengthy review by my husband: I'm a car mechanic novice, and decided to upgrade my 17-year-old car's AC after it leaked R134a during the winter, and had no clue that a device like this existed until consulting the forums. After putting my AC system together and ensuring that everything was torqued to specifications (new O-rings, compressor, accumulator, orifice expansion valve), I pulled a vacuum on the system. I then investigated in the dark for leaks... after an hour of angling a mirror into a hard-to-find place (thanks GM, the Buick Regal 1999 decided to hide the orifice replacement under the brake booster and brake module -- I'd like to know how that passed the design committee), I still couldn't find the leak. Upon putting batteries into the device, I turned the device on and walked into the garage, and the beeping started to increase frequency. I hadn't even approached the car, but then discovered that one of my valves wasn't complete shut off, and the device had picked up on the small leak. I then held the device under many of the connections, and within 2 minutes, discovered the leak in the last place I'd expect -- the easiest, most-accessible location. Dye couldn't have found this leak because it was furthest from the dye point and the compressor hadn't carried it far enough."
"But that's because it turns out the leak was INSIDE the firewall, behind the glove compartment in the dash."
"Used it to check for leaks on my vehicle."
"Used to test Freon leak for homes and cars."
"This was purchased by my Husband and said he was able to find our freon leak."
"good inexpensive unit."
